The magnetic susceptibility of a material of a rod is 499 . The absolute permeability of vacuum is 4 π × 10 - 7 H m - 1 . The absolute permeability of the material of a rod is

Absolute permeability of material of rod μ = μ r μ 0 = 1 + X m μ 0 ∴ μ = 1 + 499 × 4 π × 10 - 7 = 2 π × 10 - 4 H m - 1

The magnetic susceptibility of a material of a rod is $499$ . The absolute permeability of vacuum is $4 π \times 10^{- 7} H m^{- 1}$ . The absolute permeability of the material of a rod is

Options:

Answer:

Solution:

Absolute permeability of material of rod

$μ = μ_{r} μ_{0} = (1 + X_{m}) μ_{0}$

$∴ μ = (1 + 499) \times 4 π \times 10^{- 7} = 2 π \times 10^{- 4} H m^{- 1}$
